My apologies for my silence lately. I've been very busy with my new job, but have recently started adding some features again. I'm in the process of finishing up with those, and adding support for the latest truRIP (super)dat files, after which I hope to do a full release again. Since there are some improvements in the animations department, I also plan to update the Aeon Nox theme accordingly.
As some of you may have seen: CoinOPS is working on some new releases for PC, and they've selected RetroFE to use as a base for their work. From what I've seen so far, it should be possible to extract a theme from their work as well that people can load on top of their current RetroFE installation.
